I To (LZZ whom, it may concern.-

Be it-known that I, J oimN GUS'IA r Brenner, a subject of the King ofSweden, and a resident of Gothenburg, in the Kingdom of Sweden, haveinvented certain new and useful Improvements in Devices forCushioning'the Shockin Watenlipes by Automatic Cocks, (for which I haveobtained patents in the following countries, to wit: Sweden, No. 245,dated September9,1885; France, No. 171,291, dated Septenr ber 22, 1885;Denmark, dated September 24, 1885; Austria-Hungary No. 34,994., datedSeptember 26, 1885; Germany, No. 34,876, dated Septe1nber26,1885;Belgium, No. 70,321, dated September 28, 1885; England, No. 11,610,dated September 29, 1885, and Norway, No. 470, dated December 31,1885;)and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification,and in which Figure l is avertical sectional view of a portion of awater-closet, showing my improved device applied. Fig. 2 is a verticalsectional view of the device. Figs. 3 and 4 are similar viewsillustrating modified forms of the device. Fig. 5 is a verticalsectional view illustrating another modification. Fig. 6 is a horizontalsectional view of the device shown in Fig. 5 on the linear 0c; and Fig.7, 8, and9 are, respectively, a front view, a side elevation,and a topview of the same.

Similar letters of reference indicate corresponding parts in all thefigures,

My invention has relation to devices for cushioning the shock inwater-pipes caused by the sudden closing of automatic cocks as usuallyemployed in water closets, supplytanks, feeding reservoirs, flushingcisterns,

. and in many other cases where the servicepipes or discharge-pipesleading from the tank or reservoir are provided with automatic or selfclosing cocks. The sudden closing of these automatic cocks creates acertain shock or concussion, which affects the pipes injuriously, as itis apt to cause leakage as well as waste; and the object of my device isto overcome this sudden shock or concussion caused by the rapid closingof the automatic cock, and this I accomplish by cushioning the shock asthe cock is closed, substantially as will be or faucet, D, opens throughthe other wall of the receiver, said pipe 0 being provided with aflaring or funnel-shaped inner end, which projects over and around theinner end of the inlet-pipe B.

The upper portion of the tank or receiver above the pipes Band C may bebulb-shaped, as shown at E in Fig. 2, or of any other desiredconfiguration, as shown 011 the drawings. Referring to the constructionshown in Fig. 2, which is the construction I prefer to use for ordinarytap-cocks and not for water-closets, it will be seen that the lowercontracted portion of the tank or receiver A is provided withaperforated partition, F, which separates the main body of the tank fromthe valvechamber G, the bottom of which is provided with a valve seat oraperture, H, over which fits a ball-valve, I, preferably consisting of aball of any suitable heavy material having a rubber or other similarelastic covering.

It will be seen that the pressure of the water, partially filling thetank as it enters through the inlet-pipe B, will force the valve againstits seat, so as to close the aperture H and 00111- press the aircontained in the upper portion, E, of the tank, so that when the cock ofthe outlet-pipe or discharge-pipe O is opened the water passing from theinlet-pipe B into the flaring inner end of pipe 0 will cause the latterto operate in precisely the same manner as an injector, sucking thewater out of the tank A and valve-chamber G, so as to draw the water outof the tank.

It is obvious that the device shown in Fig. 2 will operate in preciselythe same manner if its upper portion, E, is made cylindrical and of thesame dimensions as the valve-chamber G, my only reason for making thisupper portion bulb-shaped being toincrease the capacity of theair-chamber. In some cases it is not convenient or expedient to make theupper part, E, bulb'shaped, and this part may be constructed in a verysimple and inexpensive manner from asection of ordinary pipe closed atthe top.

. It will be seen that as the water rushes out of the receiver throughpipe O,as above stated, the ball-valve I will be lifted from its seat,thereby admitting air into the tank through the aperture 11; but themoment pipe is closed the water entering the 'tank through pipe B willagain partly fill the tank, close the valve, and expend its shock upontheinclosed body of air, whichthus operates to cushion the shock andprevent it from spreading and being communicated to the pipes.

'In Figs. 3 and 4 of the drawings I have shown the modification which Iconsider most suitable for water-closets and similar purposes.

. By reference to the said figures it will be seen that thevalve-chamber is placed at the upper end of the tank, and the-ball-valveis in this case a light floating ball, which'may be forced up againstthe valve-seat by the water rising in a tube, J, which projects from thevalvechamberdown into the body of the tank, and through which tube thewater is forced upward by the air being compressed within the tank.

In Fig. 3 the valve-chamber is provided at its upper end with a curvedtube, J, which will admit air and prevent impurities from entering,while in Fig. 4 the valve-chamber is provided with a partition, K, whichhas an aperture opening into a chamber, L, provided at one side with anaperture and curved airtube, M. Both these devices operate in 'preciselythe same manner.

In Fig. 5 is shown a vertical sectional view of still anothermodification, a horizontal sectional view of the same being shown inFig. 6, a front view in Fig. 7, a side elevation in Fig. 8, and a planor top view in Fig. 9. In this modification of my device the floatingball-valve is confined within a valve-chamber at the lower end of a box,0, which is inserted through the top of the tank A, its upper projectingpart being provided with an air-inlet, M. The inlet pipe B passestransversely through the tank, entering the same at one end, passing outat the other end, and having at its middle, inside the tank, aprojecting nozzle, B, which projects into the flaring mouth of thedelivery-pipe C. This construction will be found advantageous where itis desired to continue the flow of water through pipe Bas, for example,whereanumber of these devices are connected or combined in a continuoussystem.

In Fig. 1 I have shown one method of connecting the tank or receiver Ato the bowl of a water-closet and to the service-pipe, and from what hasalready been stated the operation of the device in this connection willrequire no further explanation.

Having thus described my invention,I claim and desire to secure byLetters Patent of the I UnitecKStates- 1 7o 1. In a device forcushioning the shock in high-pressure water-service pipes caused byclosing the cooks, the combinationof a receiver provided with aninwardly-opening valve, an outlet-pipe having an outwardly-flaring innerend, and an inlet-pipe entering the flaring portion "of saidoutlet-pipe, as and for the purpose set forth.

2. In a device for cushioning the shock in high-pressure water-servicepipes caused by closing the cooks, the combination ofa receiver, aninlet-pipe entering the receiver at one side, an outlet-pipe having aflaring inner end fitting around the inner end of the inlet-pipe andpassing out through the opposite side of 8 the receiver, a valve-chambercommunicating with the lower portion of the receiver and having avalve-aperture opening to the outside, and a ball-valve fitting upon theinner side of the valve-aperture and adapted to be 0 forced against thesame by the pressure from within, as and for the purpose shown and setforth.

3. In a device for cushioning the shock in high-pressure water-servicepipes caused by 5 closing the cooks, the combination of a receiverhaving a valve-aperture in the lower end, a heavy ball-valve fittingupon the valve-aperture, an inlet-pipe entering the lower portion of thereceiver, and an outlet-pipe having a flaring inner end'fitting aroundthe inner end of the inlet-pipe and projecting out through the opposite,side of the receiver, as and for the purpose shown and set forth.

4. In a device for cushioning the shock in high-pressure water-servicepipes caused by closing the'cocks, the combination, with a receiverprovided with inlet and outlet pipes, ofa valve-chamber located abovesaid receiver and provided with avalve-aperture at its top, a tubeprojecting downwardly from said chamber, and a floating ball-valve forclosing said aperture, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature 1 I5 in presence of two witnesses.
